Secure Data Transfer by Implementing Mixed Algorithms

Abstract

Nowadays, data sharing is a common need for the humans to transfer information. There are different security threats to be overcome while transmitting data in Internet. Cryptography helps to solve all the issues that are generated. The objective of this paper is to enhance the security level by using mixed security algorithms. This work is proposed of three parts—playfair algorithm of 9 × 6 matrix, RSA algorithm, and an XOR operation. The mixed algorithm enriches the security strength of individual symmetric and asymmetric algorithms. Also, this work yields good results in many parameters like message strength, key strength, encryption, and decryption time. The idea of mixed algorithms in cryptography is helpful for researchers in the nearby future.
